1. Pick a number.
2. Reverse its digits and add this value to the original number.
3. If this is not a palindrome, go back to step 2 and repeat.

Let's view this Reverse and Add sequence starting with 64:

64+ 46
step 1: 110+ 011
step 2: 121

64 takes 2 iterations / steps to resolve into a 3 digit palindrome.

REVERSAL-ADDITION
PALINDROME
RECORDS

Most Delayed Palindromic Number for each digit length(Only iteration counts for which no smaller records exist are considered.
My program records only the smallest number that resolves for each distinct iteration count.
For example, there are 18-digit numbers that resolve in 232 iterations,
higher than the 228 iteration record shown for 18-digit numbers, but they were not recorded,
as a smaller [17-digit] number already holds the record for 232 iterations.)
